Initial in the space provided to indicate that the following design requirements have been met and supporting documentation is attached. If the applicant has designated an agent in the Stormwater Management Permit Application Form, the agent may initial below. Attach justification if a requirement has not been met. Applicants Initials ah a. System is located 50 feet from class SA waters and 30 feet from other surface waters. �L b. System is located at least 100 feet from water supply wells. C. Bottom of system is at least 2 feet above the seasonal high water table. ' d. Bottom of the system is 3 feet above any bedrock or impervious soil horizon. e. System is not sited on or in fill material or DWQ approval has been obtained. £ System is located in a recorded drainage easement for the purposes of operation and maintenance and has recorded access easements to the nearest public right-of-way. g. Drainage area for the device is less than 5 acres. h. Soils have a minimum hydraulic conductivity of 0.52 inches per hour and soils report is attached. i. System captures and infiltrates the runoff from the first 1.0 inch of rainfall (1.5 inch event for areas draining to SA waters ). Design volume and infiltration calculations attached. j. System is sized to take into account the runoff at the ultimate built -out potential from all surfaces draining to the system, including any off -site drainage. Calculations attached. Mhk. All side slopes stabilized with vegetated cover are no steeper than 3:1 (H:V). 1. A pretreatment device such as a catch basin, grease trap, filter strip, grassed swale or sediment trap is provided. m. Bottom of the device is covered with a layer of clean sand to an average depth of 4 inches or dense vegetative cover is provided. n. Vegetated filter is provided for overflow and detail is shown on plans (Required minimum length is 50 feet for SA waters, 30 feet for other waters). o. Flow distribution mechanism within the basin is provided. MyN p. A benchmark is provided to determine the sediment accumulation in the pretreatment device. q. Runoff in excess of the design volume bypasses off-line systems (bypass detail provided). r. System is designed to draw down the design storage volume to the proposed bottom elevation under seasonal high water conditions within five days. A soils report and all pertinent draw -down calculations are attached. s. Plans ensure that the installed system will meet design specifications (constructed or restored) upon initial operation once the project is complete and the entire drainage area is stabilized. Form SWU-103 Rev 3.99 Page 2 of 3 Attachment to INFILTRATION BASIN SUPPLEMENT For Harbinger Center C. The basin bottom is below the water table. This is an existing basin with a permanent pool depth of±2.75'. All infiltration is calculated through the side walls. f. The system is located entirely on the project site and is adjacent to a paved drive aisle which will provide easy access to the basin. The overflow for the basin drains to an existing ditch located on the eastern property line. g. The drainage area for the site is 10.44 acres. The system was constructed in the late l 980's. We are working with an existing situation. This system captures and infiltrates the first 2 inches of rainfall. Most of the stormwater is routed through catch basins, but some of the water surface flows to the basin by means of concrete valleys and curb and gutter. n. No vegetated filter is provided on site, but the overflow will discharge into an existing ditch that will route the flow approximately 700' before it enters wetlands of the Currituck Sound. q. No bypass was provided because we have increased the storage to include the first 2 inches of runoff and an overflow weir has been added to route excess rainfall through the pond. IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT 1. After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion, trash accumulation, vegetative cover, and general condition. 2. Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow vegetated cover to maintain a maximum height of six inches, and remove trash as needed. 3. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow structures for blockage and deterioration. Remove any blockage and repair the structure to approved design specifications. 4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored to the original design depth without over -excavating. Over -excavating may cause the required water table separation to be reduced and may compromise the ability of the system to perform as designed. Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will adversely impact water quality (i.e. stockpiling near a stormwater treatment device or stream, etc.). A benchmark shall be established in the pretreatment unit. The benchmark will document the original design depth so that accurate sediment accumulation readings can be taken. The measuring device used to determine the depth at the benchmark shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the design depth reads feet in the pretreatment unit, the sediment shall be removed from both the pretreatment unit and the infiltration basin. 5. If the Division determines that the system is failing, the system will immediately be repaired to original design specifications. If the system cannot be repaired to perform its design function, other stormwater control devices as allowed by NCAC 2H .1000 must be designed, approved and constructed. I acknowledge and agree by my signature below that I am responsible for the performance of the five maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any changes to the system or responsible party. Print Name and Title: L I l i a s J.
